Starr Pass loop that will test your ability to clean chunky, techy climbs. What you dont clean today, you can try again next ride. Not for everyone. My favorite section has been called "the worst trail in Tucson." If your a fan of Brown Mtn further west, I reccomend this route to you.

 People dump all over my favorite trails too. It's all good. Nice eye on this loop, though personally I'd take Sunset Pass from Explorer so I could hit 360 Vista - my favorite in Robles Wink - on the way to BB/Flight Path.
